Term
Lymph from right upper quadrant feeds into what duct?
Definition
Right lymphatic duct
Term
Lymph from the body (except right upper quadrant) feeds into what duct?
Definition
Thoracic Duct
Term
The Righ Lymphatic Duct and the Thoracic Duct feed into what veins
Definition
The respective Subclavian Veins
Term
What is the daily capillary outflow?
Definition
3 L (more than venous system can handle)
Term
what is lymph made of?
Definition
Water and dissolved proteins like albumin
Term
What type of blood cell do lymph nodes have a lot of?
Definition
White Blood Cells - Has B and T lymphocytes to phagocytose most of the foreign material
Term
Why do we look at lymph nodes to check for metastasis
Definition
They have a lot of T-cells that fight tumors
Term
What is the basic idea of Starling's theory of fluid dynamics?
Definition
Fluid flows from area of high pressure to area of low pressure
Term
What is plasma hydrostatic pressure (PHP)?
Definition
The pressure inside capillaries that forces fluid out into the tissues
Term
What is Tissue hydrostatic pressure? (THP)
Definition
Pressure that forces fluid out of the tissues
Term
What is Plasma colloidal osmotic pressure (PCOP)?
Definition
Protein in the plasma that pulls fluid from tissues into capillaries
Term
What is Tissue colloidal osmotic pressure (TCOP)?
Definition
Fluid is pulled from capillaries into tissues by the solute concentration of plasma proteins in the tissues
Term
Which two pressures pull fluid from Capillaries --> tissues?
Definition
Plasma hydrostatic pressure
Tissue colloidal osmotic pressure
Term
What two pressures send fluid from
tissues ----> capillaries?
Definition
Tissue hydrostatic pressure
Plasma colloidal osmotic pressure
Term
What makes lymph move
Definition
-skeletal muscle contraction
-arteriole pulsing
-smooth muscles in walls
Term
What percent of fluid goes where?
Definition
10% lymp
90% venous
Term
What is the difference between primary and secondary lymphedema?
Definition
-Primary - born without vessels/
abnormal vessels
-Secondary - Caused by blockage
Term
Lymphedema is characterized by...
Definition
Abnormal accumulation of protein rich lymph fluid in the extracellular spaces
Term
Stemmers sign for lymphedema
Definition
To perform it, try to pinch and lift a skinfold at the base of the second toe or middle finger. If you can pinch and lift the skin, Stemmer’s sign is negative. If you can’t, the sign is positive.
Term
Medications for Lymphedema
Definition
Benzopyrones - increases proteolysis and macrophage activity
*Diuretics are not helpful
Term
Lymphedema precautions
Definition
-healthy weight
-prevent trauma to area of lymph node removal
-No BP in affected arm
-Keep skin/nails clean
-Avoid trauma to affected area
-Nothing tight-fitting
-etc
Term
Lymphagitis
Definition
-infection of lymphatics
-Treat w/antibiotics
Term
Signs of lymphagitis
Definition
-rash
-red blotchy skin
-Itching
-discoloration
-warmer skin
-pain
-sudden onset of fever/chills
Term
Lipedema
Definition
Deposits of subcutaneous adipose tissue
Term
Which is spontaneously reversible at stage one?
Definition
Lymphedema
Term
Main things to remember about lymphedema...for comparison
Definition
-Pooling of fluid
-Affects feet
-Pitting edema @ first.....then became hardened over time (fibrotic)
-Can be born w/out lymph nodes
-Arms AND legs
-unilateral
-stemmons sign
-disruption of lymph system
-compression treatment
Term
Main things for lipedema.....for comparison
Definition
-Pooling of fat
-mostly women
-does not affect feet
-spongy feel to tissue
-pitting edema common
-Edema increases thru day
-Onset at puberty
-symmetrical
-legs only
-no stemmers sign
-genetic component
-hormonal disorder
-lower level of compression treatment
Term
How many stages of lymphedema? Quickly describe...
Definition
Stage 1 - spontaneously reversible
Drain with elevation
Soft - pitting edema
Stage 2 - spontaenously irreversible
Spongy & nonpitting
increase in size
Intervention for reversal
Stage 3 - lphostatic elephatiasis
Does not reverse
Hard/fibrotic tissue
